ACETYLENE-GAS GENERATOR.

SPECIFICATION forming part of Letters Patent No. 633,592, datedSeptember 26, 1899. Application filed Novemher 17, 1898. Serial No.696,698. (No model.)

To all whom it may concern:

Be it known that I, ANDREW HOLLAND, a subject of the Queen of GreatBritain, residing at Ottawa, in the county of Carleton, in the Provinceof Ontario, Canada, have invented a new and useful Improvement inAcetylene-Gas Machines, of which the following is a specification.

My invention relates to improvements in acetylene-gas machines; and theobject of the invention is, first, to provide one especially adaptableto railroad use, such as car-lighting and locomotive head-lighting,where the machine is subject to the vibration, oscillation, and frequentshocks to the train or locomotive; secondly, to provide a machine inwhich the gas-pressure to the burner is sufficient to overcome the draftfrom the door or window; thirdly, to provide amachine in which there isno danger of the gas exploding, the generation of gas not exceeding acertain limit, which limit is regulated by the pressure of water in thewater-chamber, and, fourthly, to provide a machine in which the supplyof water is very gradual, thus overcoming any danger of the waterfreezing in winter-time, the water supplied being heated by thegenerating action of the gas.

To carry out these objects, my invention consists in the novelarrangement and construction of parts, as hereinafter more particularlyexplained in detail.

In the drawings like letters of reference indicate corresponding partsin each figure.

Figure l is a perspective view of my machine, showing one generator insection and showing it in form adaptable to the lighting of cars. Fig. 2is a section through the gasholder and the water-chamber. Fig. 3 is asectional detail of the check-valve. Fig. 4 is a cross-section throughFig. 3 on the line a b. Fig. 5 is a similar view on the line at A is thebody of the car, A is the floor thereof, and A the walls.

B is a cylinder having end' plates 1) 1), secured together by rods andbolts 13 b respectively.

b is a partition dividing the cylinder into two compartments 0 and D.The chamber 0 is filled with water and the chamber D partiall y so.

d is an opening through which the chamber D may be supplied with water.

d is an outlet-pipe for draining off the impure water.

E is a feed-pipe leading from the lower chamber, but from above theWater contained therein, to the gas-jets and provided with a suitablecock 6 for closing the same.

F is a pipe extending down into the water in the lower chamber, itsopposite end being connected to the generator by the branch pipes f. Thebranch pipes f are provided with suitable cocks f to cut off the waterflowinginto the generator. The pipe F passes loosely through the head ofthe cylinder B, and an air-vent is thus provided for the latter aroundsaid pipe.

Gisacross-pipe connectingthe upper chamher 0 to the exterior portion ofthe pipe F.

H is a check-valve placed in the pipes G, formed of a casing h, ascrew-top 7t, and openings 72. 72, in the top and bottom thereof.

h is a valve-seat concave in form, gradually merging into the squareportion 71 h is the ball of the valve.

The pipe F is also provided with a cock f to cut off the supply of gasto the gas-holder.

of the cylinder B. The generators are bolted to the door of the car bymeans of bolts a.

K are the lids of the generators, suitably hinged thereto.

76 7care a pair of lugs formed on the lid K and having between them thelever 70, hav ing a cam-shaped end 70 k is a lug formed on the body ofthe generator and extending between the lugs formed on the lid and whichserves to form a fulcrum for the lever 7c. The lever 7c is secured bythe link is, secured to the generator.

L is the carbid-holding basket, suitably supported in the generator J bylegs Z.

Having now described the principal parts involved in my invention, Ishall describe the operation of the same.

The chamber 0 is filled with water and the chamber D partially so. Thecock I is then opened and allowed to remain open during the operation ofthe machine. WVater flows through the pipes G F f to the generator,

loo

which has its cock f open. The gas passes through the pipes f F into thegas-chamber, passing in this operation through the Water in the chamberD, which serves to purify it, and it is then ready for consumption. Thewater in the chamber D forms a cushion for the gas compressed in thespace above its surface, serving to produce an even feed to thegas-jets. As soon as the gas-pressure falls below the water-pressure inthe chamber O the check-vaive H is opened by such water-pressure, thusfeeding more water to the generators J. WVhen the gas-pressure overcomesthe water-pressure, it closes the valve H, cutting off the water-supply.

Vhat I claim as my invention is In combination with a generator, avertically-arranged cylinder having a gas-chamher in its lower end and aWater-chamber in its upper end, a feed-pipe leading from the gas-chamberto the point of consumption, a pipe leading from the generator to thegaschamber, a branch pipe tapping the gas-pipe
